We have a spectrafire. It does have a fan, only one setting, it is not adjustable. The fan should continue to run for about a minute after turning the heat off, to cool the heater down. You can adjust everything else that can be changed on the fireplace with the remote but, you cannot control the temp setting. Temp setting can only be set at the control panel on the fireplace, which I think is strange. Temp and on and off is what gets changed most often.
